The present work provides length‐weight relationships (LWRs) for fish species captured around artificial offshore reef deployed 5 km from Guaxindiba Port, northern Rio de Janeiro, Brazil. The fish were captured during two sampling periods each year between 1996 and 2017 using bottom gill nets (25 m_length × 3 m_depth; 30 mm mesh). The fish were kept on ice and the biometric data, including total length (cm) and total wet weight (g) were determined in the laboratory. A total of 16 species belonging to 10 families were analyzed with Sciaenidae being the species richest family (5 spp) in the samples. The new value of LWRs for Sphyraena guachancho and new maximum sizes recorded for seven species highlight the scarcity of information on biological aspects of South America coastal fishes. These LWRs should assist fisheries scientist and managers to complement their further studies of population parameters to improve management decisions.

在人工近海珊瑚礁（巴西里约热内卢北部）捕获的鱼类物种的长度与重量的关系

目前的工作为在距巴西里约热内卢北部瓜辛迪巴港5公里处部署的人工近海礁石周围捕获的鱼类提供了长度重量关系（LWR）。在1996年至2017年期间，每年使用底部刺网（25 m_长 ×3 m_深度； 30 mm网眼）在两个采样期内捕获鱼。将鱼放在冰上，并在实验室确定包括总长度（cm）和总湿重（g）在内的生物特征数据。共分析了属于10个科的16种，其中S科是样品中物种最丰富的科（5 spp）。LWRs对Sphyraena guachancho的新价值新记录的七个物种的最大尺寸凸显了南美沿海鱼类生物学方面信息的匮乏。这些LWR应协助渔业科学家和管理人员补充其对种群参数的进一步研究，以改善管理决策。
